This QR code reader decodes codes from image files or screenshots pasted from your clipboard, then classifies the content and offers the right action. Everything runs locally — a privacy-safe scanner for anyone who gets QR codes on a computer, not a phone.

How QR Codes Work

A QR code stores data in a grid of black and white modules; the three large corner squares are finder patterns so scanners can orient the code even when tilted. Its real strength is Reed-Solomon error correction — the math used on CDs — which lets a code survive up to 30 percent damage. That is why brands can print logos in the middle of a code, and why a blurry screenshot often still decodes. The content is plain text with conventions: WiFi codes use a WIFI: prefix that phones know how to interpret.

How to Use

  1. Drag an image containing a QR code onto the upload area, or click to browse.
  2. Or click the paste button and paste a screenshot from your clipboard.
  3. The decoded content appears, classified by type: URL, email, phone, WiFi, SMS, text, or contact.
  4. Use the action buttons to open a link or copy the text.

Use Cases

Decode a code from a PDF invoice or slide deck without reaching for your phone. Check where a QR link points before opening it — a simple habit against QR phishing. Extract WiFi credentials from a printed code, or verify a code you generated yourself.

Frequently Asked Questions

What types of QR codes can this reader decode?

The reader can decode all standard QR code content types including URLs, email addresses, phone numbers, WiFi configurations (WIFI:S:...), SMS messages, plain text, and vCard contact information. The content is automatically classified and appropriate action buttons are shown.

Why isn't my QR code being detected?

Common reasons include: the image is too blurry or low resolution, the QR code is partially obscured, the image contrast is too low, or the image format is unsupported. Try using a clearer, higher-resolution image and ensure the QR code is fully visible.

Are my scanned QR codes stored anywhere?

No. All decoding happens entirely in your browser. QR code images and their decoded content are never uploaded to any server. Your privacy is fully protected.
